A safety breathing apparatus has a sensor for measuring the difference in pressure between two point 1a, 1b in the gas delivered to a head unit 9. The sensor is used to measure the difference in the pressure of the gas supplied through the apparatus between the two points in the gas flow, and the pressure difference is then used to calculate the gas flow rate.

A ventilation system includes an electrochemical filter for depleting alkyl phenols, especially 2,6-diisopropyl phenol, in breathing gas. A method uses the filter for removing alkyl phenols, especially 2,6-diisopropyl phenol, from breathing gas.

Breathing treatment device (100) for therapeutic use, the device comprises a motorized air recirculation system, a set of filters for air purification (10a, 10b, 10c, 10d), an ultraviolet ray sterilizer and an plasma electrostimulator, the device characterized in that it comprises means for the ejection of air in laminar flow (6) with noise emission between 0 and 5 dB; means for redirecting the laminar flow towards the head of the patient, a stabilizer (1), a multifilament diffuser (2), one or more UV-C LEDs (11).

Provided is a filtering facepiece respirator. The respirator includes a mask body having an anterior side portion, a posterior side portion, a middle portion, a first side portion, a second side portion, a top side portion, a bottom side portion and outer edge portions. The respirator further includes a primary port positioned at the anterior middle portion of the mask body and a detachable primary port adapter which is positioned over and engages the primary port. The respirator may further include an oxygen port and oxygen port adapter and a luer port and luer port adapter.

A respiratory therapy apparatus is operable to deliver multiple types of therapy to a patient. The apparatus includes a main housing and a nebulizer tray that selectively attaches to a bottom of the main housing. The apparatus also includes a filter housing unit having an antenna surrounding a pneumatic passage and a transponder chip coupled to the antenna. The main housing has also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators. In some cases, instantaneous impedance or conductance may be used to assess re-connection of a patient circuit, detection of flow starvation, determine breath shape for triggering and cycling and to detect patient or circuit obstructions.

A diagnostic device is disclosed for characterisation of particles from a patient's airways, such as a lung, when ventilated by a ventilator, and/or for control thereof, comprising a particle detecting unit configured to be connected to a conduit for passing expiration fluid from said patient, for obtaining data related to particles being exhaled from said patient's airways.

A hydrogen generator comprises an electrolytic module, a hydrogen water cup, an integrated passageway device and an automatic diversion device. The electrolytic module is configured to electrolyze water and generate gas comprising hydrogen. The hydrogen water cup is configured for containing liquid, and injecting the gas comprising hydrogen into the liquid to form hydrogen liquid. The integrated passageway device is stacked above the electrolytic module, and includes an inlet gas passageway, an outlet gas passageway and a gas communication passageway. The automatic diversion device is configured for selectively communicating the inlet gas passageway, the hydrogen water cup and the outlet gas passageway or selectively communicating the inlet gas passageway, the gas communication passageway and the outlet gas passageway.

Aspects of the invention include devices, systems, and methods for enhancing a user's sleep. A flexible frame supports a flow manifold which can be used in unison with adjoined or adjacently integrated supportive members utilized to create soft objects of various designs and materials. These types of objects can be in the form of a pillow, mattress topper, even a child's stuff animal and other various stationary and portable soft sided padded embodiments as disclosed in this application. These various designs and embodiments house an integrated flow delivery system which is delivers concentrated, pressurized, and or altered gaseous flowing elements in a controlled and fluidic manner as to help address certain types of sleeping and breathing issues during their resting and sleep states.

A patient isolation unit (PIU) for use in marine rescues. The PIU of this invention is useful to safely transport personnel exposed to, or potentially exposed to, an identified and/or known infectious agent or chemical warfare agent (CWA) on marine vessels and/or aircraft such as Coast Guard boasts, cutters and aircraft. The PIU has a generally tapered tubular shape compatible with wire rescue baskets conforming in shape to the human body and into which an injured, sick, or disabled person can be safely strapped, such as the Stokes litter rescue basket for hoisting and fit in rotary wing aircraft.
